This utility model discloses a mud crab spawning and hatching device, including a cement pool, which comprises a pool body with a permeable stone slab at the bottom. A hole is opened at the bottom right side of the pool body, and a drain pipe is installed inside the hole. A water supply component includes a water quality sensor located on the left side of the pool body. An air supply component includes a dissolved oxygen sensor located at the front of the pool body. A heating component includes a temperature sensor located at the front of the pool body. A movable component is installed at the top of the pool body, with a polycarbonate panel fixedly connected to its inner side. This utility model, through the structural design of water quality, dissolved oxygen, and temperature sensors, combined with water supply, air supply, and heating systems, can monitor and adjust key environmental parameters in the hatching pool in real time. The water quality sensor, linked to a solenoid valve, intelligently changes water to prevent water quality deterioration. Microporous aeration heads uniformly increase oxygen, ensuring balanced dissolved oxygen distribution. Heating pipes, in conjunction with the temperature sensor, maintain a stable water temperature.
